1. A computer-implemented method for synchronizing a master press and a slave press, the method comprising:
receiving a signal associated with the master press printing a first frame on a first web;
determining a point in time at which the slave press should begin printing, on a second web, a second frame corresponding to the first frame, wherein the determining is based on the signal associated with the master press and a first distance between the slave press and a downstream location at which the first and second webs converge; and
operating the slave press to begin printing the second frame at the point in time so that the first frame and the second frame are to arrive at the downstream location at a substantially same time while the slave press is positioned in parallel with respect to the master press.
